This invention relates to dripping devices, and W ch may be adjust d to u ate the ow of more particularly to a type of dripping device q d to suit conditions. that can be used by the public in the distribution The 1iqu d pping from t co enters and dispensing of liquids. a o p t, partly fil e w filtering means,

5 An object of the invention is to provide a de-' directly below the d P-C h pp 5 l vice with-means provided for dripping liquid, one a a p p adi int h l w st tank drop at a: time to moisten the fingers or hands of through ntake valve 3|, Where the tank fills the user. i i up to a level as indicated by the line 2|. As the Another object, 0f the invention is to enable a, liquid level rises in the storage tank 23, 9, float 22 personto moisten his fingers with a filtered liquid, ses w th it. s float 2 is guided bye rod 23 10 without coming in contact with a moisture laden an as a tical Sliding otion. When a preobject, previously used by other persons, thereby determined liquid level has been reached, the eliminating the possible contact with disease float 22 contacts the pin 24 onthe rod 23 and germ i pushes the rod 23 upward in its guides 25 and 26 Another object of the invention is to provide a andby mean o a yp arm 0n the mer- 15 means of forcing the dispensed filtered liquid that cury switch support 28 which pivots on a pin29 is not used, up into thesupply reservoir, to" be and is supported by a brace or bracket 30, tilts made to drip over again, until the entire supply the mercury container 41 making a contact on is exhausted; POSllS BIG. and 32.

As the air in tank 35 cools it con- 55 tracts and new air is drawn into the tank through intake valve 4! incased in a cover 43 having holes 42 to allow air to enter. The liquid when it leaves tank through pipe I6, is prevented from coming out of the hopper l8 by the intake valve 3| which closes up against pressure, and the air in tank is kept from escaping through intake valve 4| which is constructed similar to Fig. 5 and Fig. 6. However any other conventional type of intake valve may be used, as the method of operation of the entire unit as a unit would remain the same. 7

Having thus described our invention, what we claim and what we ask for Letters Patent from the United States is:

1. In a dripping device, means for containing and releasing a fluid in drip form, an open con tainer for catching and containing the drip having an outlet with a check valve therein leading to a closed tank, and separable means for supplying gas pressure to raise the drip from the tank to the containing and releasing means for re-use, when the fluid in the tank reaches a predetermined level.

2. In a dripping device, means for containing and releasing a fluid in drip form, an open container for catching and containing the drip having an outlet with a check valve therein leading to a closed tank, and separable means for supplying gas pressure to raise the drip from the tank to the containing and releasing means for reuse, when the fluid in the tank reaches a predetermined level, said gas pressure supplying means comprising an auxiliary gas tank, communicating with said closed tank, and means in said auxiliary, gas tank for heating said gas.

3. In a dripping device, means for containing and releasing a fluid in drip form, an open container for catching and containing the drip having an outlet with a check valve therein leading to a closed tank, and separable means for supplying gas pressure to raise the drip from the tank to the containing and releasing means for re-use, when the fluid in the tank reaches a predetermined level, said gas supplying means comprising an auxiliary tank having valve means for entry of air thereinto, and means for heating said air when the fluid in the tank reaches the predetermined level.

4. In a dripping device, means for containing and releasing a fluid in the form of drip, an open container for catching and containing the drip having an outlet with a check valve therein leading to a closed tank, and means for heating a gas to place the same under pressure to force the fluid from the tank to the containing and releasing means for re-use, when the fluid in the tank reaches a predetermined level, comprising an electrical heater, switch means positioned on the exterior of the tank for operating said heater, and float means positioned in said tank for controlling said switch means.

5. In a dripping device, means for containing and releasing a fluid in drip form, an open container for catching andcontaining the drip having an outlet with a check valve therein leading to a closed tank, and means for supplying gas pressure to raise the drip from the tank to the containing and releasing means for re-use, when the fluid in the tank reaches a predetermined level.

6. In a dripping device, means for containing and releasing a fluid in drip form, an open container having filtering means therein for catching and containing the drip and having an outlet with a check valve therein leading to a closed tank, and means for supplying gas pressure to raise the drip from the tank to the containing and releasing means for re-use, when the fluid in the tank reaches a predetermined level.
